Javascript成爲做財產以後的onclick除了HREF =「＃」和HREF =「<javascript>」標籤

Question

如何做onclick任何<a>標籤除了href="#"和href="javascript"標籤

我有一個劇本，但它也工作在任何標籤href="#"類似的標籤。我想排除href="#"和href="javascript"標籤。

這是我當前的腳本

window.addEventListener('load', function(){ 
 
      if (!document.getElementsByTagName) return; 
 
       var anchors = document.getElementsByTagName("a"); 
 
       for (var i=0; i<anchors.length; i++){ 
 
        var anchor = anchors[i]; 
 
        if(anchor.getAttribute("href")) 
 
          anchor.target = "_blank"; 
 
       } 
 

 
    function tabunder() { 
 
    \t \t window.location = 'https://example.com' ; 
 
    \t } 
 
     
 
     
 
    for (var i=0; i<anchors.length; i++){ 
 
    \t anchors[i].onclick = tabunder; 
 
    } 
 

 

 
    });

嘗試添加if語句象下面這樣：

var anchors = document.getElementsByTagName("a"); 
for (var i = 0; i < anchors.length; i++) { 
    var anchor = anchors[i], t = anchor.getAttribute("href"); 
    if (t){ 
    if(t === "#" || t === ""){continue;} 
    anchor.target = "_blank"; 
    } 
}
